-## Todo
+### New DSL (v0.4.0+)
 
-`sudo` has a `-A` option to accept password via an external program (maybe
-graphical): support this feature.
+For simple operations, you can use the convenience method:
+
+```ruby
+require 'sudo'
+
+# Accepts the same options as Wrapper.run:
+Sudo.as_root(load_gems: false) do |sudo|
+  sudo[FileUtils].mkdir_p '/root/only/path'
+  sudo[File].write '/etc/config', content
+end
+```
+
+### Configuration (v0.4.0+)
+
+Configure global defaults:
+
+```ruby
+Sudo.configure do |config|
+  config.timeout = 30           # Default: 10 seconds
+  config.socket_dir = '/var/run' # Default: '/tmp'
+  config.sudo_askpass = '/usr/bin/ssh-askpass'  # For graphical password prompts
+  config.load_gems = false      # Default: true - whether to load current gems in sudo process
+end
+```
+
+### Graphical Password Prompts (v0.4.0+)
+
+Set `sudo_askpass` to use graphical password prompts via `sudo -A`:
+
+```ruby
+Sudo.configure do |config|
+  config.sudo_askpass = '/usr/bin/ssh-askpass'
+  # Or use the auto-detected constant for convenience:
+  # config.sudo_askpass = Sudo::ASK_PATH_CMD
+end
+
+# Or per-wrapper:
+Sudo::Wrapper.run(sudo_askpass: '/usr/bin/ssh-askpass') do |sudo|
+  sudo[FileUtils].mkdir_p '/secure/path'
+end
+```
+
+### Timeouts (v0.4.0+)
+
+Configure connection timeouts:
+
+```ruby
+# Global configuration
+Sudo.configure do |config|
+  config.timeout = 15  # Wait up to 15 seconds for sudo process to start
+end
+
+# Or per-wrapper
+Sudo::Wrapper.run(timeout: 5) do |sudo|
+  sudo[SomeClass].time_sensitive_operation
